To aZZ whomz't mag/concern:

Be it known that I, JOH HENRY'BIABSH, subject of the King of Great Britain and Ireland, and resident of Swinton, Manchester, in the county of Lancaster, England, have invented an Improved Yarn Clearer and Cleaner,

is a specification. v

gIn' clearing or cleaning apparatus ,for yarns it is important that the pairs of clearer knives, whilst maintaining their efficiency for "the removal of slubs, or foreign matter from the yarns, shall be capable of very accurate, adjustment relatively to each other, so that they may be-adjusted to suit various kinds of yarn according to the quality or comparative cleanness of the latter. Y These improvements relate to such apparatus for clearing or cleaning yarn, and

have for object the provision of such an apparatus which shall be simple and will admit of ready and simultaneous adjustment of the clearing or cleaning means whilst at the same time ensuring that such means shall maintain their efficiency in operation. In carrying my invention into effect, I provide a clearer or cleaning apparatus comprising a rotatable shaft having circus lar clearer-discshereinafter referred to as knivese mounted thereon; a second shaft parallel to the first, also rotatable and with means for longitudinal adjustment of said shaft, and having mounted thereon circula'r clearer knivesto co-actwith the clearer knivesi'mounted on the first shaft. The second shaft is slidable longitudinally in its bearin'gs,-and the longitudinal adjustment thereof'may be effected whilst still allowing of free rotation of the shaft, as-will be hereinafter shown. t

The improvements will now be fully described with reference tothe accompanying drawings, wherein Figure l, is a plan of the complete apparatus. Z i V Figure 2, is an elevation of same."-

Figure Y3, isa section on line. 3-3 of Figure2: a ,1 V Figure 4, is a sectional view of the adjusting means for the second shaft above referred to; and Figure 5 a sectional view of an end bearing for the first shaft.

I Referring to the drawings, Figures 1 and r 2, 1 13 the base ofthe apparatus, providedwith a side frame 2 formed withbearings of which the following in whichthe necks of the various shafts are 7 ournalled as shown; 3 ,1s a. first motion.

shaft journalled'as indicated, and passing through and being supported bya bearing 4 as shown in Figure 1. It has keyed upon it the face bevel 43, or other desired-toothed wheels which may transmit action to -the shaft 8 from any convenlentsource. The

shaft 3-has keyed thereon the spur wheel Sgearing with aspurwheel 6' on ya further shaft 7 parallel to the shaftB, and this spur-wheel 6 gears with a still further spur wheel 6 on shaft Sparallel to the othertwo shafts. The shafts 7 and 8 will be respec tively referred to hereinafter as the first clearershaft and the second clearer shaft.

The first and second clearer shafts 7 and 8 are journalled as; stated above inbearings-iin the side frame 2,-and their other extremities are journalledin bearings 9, 1n the oppos te side frame 11,. On each shaft 7 and. 8 are mounted the clearer knives 12, 13,each knife being fitted .upon its shaft many convenient manner, as for instance -tates, theshafts 7 and 8 will also rotate but infiopposite directions the one to the other, I

and the adjacent annular faces of the clearer knives 12 and= 13 form 7 an effective clearing device for yarns passing therebetween.

Th secondcleare'r shaft 8 is-adapted to rotate only. butthe first clearer shaft is adapted to be adjusted longitudinally to adjust the distance between any knife 12 and the otherknife18 f a pair. The means for'adjustment'are shown indetail in Fig- ,ure 4.; In thatfigure, 7 is the shaft and 9 the journal or" housing for the end thereof. Uponthe shaft 7 is; secured a 'collar16, having arecessed face which" with .a lco'rrespondingly recessed face on aloose'collar 17 forms a race forfthe balls .17. j housing is internally threaded atv 18 toreceive a threaded plug 19, which'isicentrally recessed at 20 ;to receivethe single thrust The i ball 21 supported inits recess by the shaft diameter.

Atthe same time, the" thrust ball bearing means allow-for the re; tation of the shaft7.

Thetwo shafts 7 and 8'are'formed of the same metal andof the same length and They have therefore the'same cubic content, and will expand and contract equally as a result'o f temperature changes, a very important consideration, as any motio in expansion or contraction be;

tween the two shafts 7 and '8 would affect ing or housing, and 24 a collar secured upon the end'of said shaft. Bearing balls 25 are interposed between the collar 24 and the en d wall of the housing 10. vA plug 26 is fitted within thehousing, said plug being recessedf as shown for the reception of a ball '27 which rests therein and bears againstthe end of the shaft 8 byfthe' pressure upon'thc plug 26 of the helicalspring 28 secured at one extremity t0 the saidplug. The spring 28 bears, at its other extremity, against a screwed end plug or closer 29, and the latter by means of a suitable tool inserted in slot 30, may be manipulated to vary the pressure of the said spring if desired,

' As a result of this constructionno change can takeplace 1n the space between a pair of knives except that effected purposely by the adjustments of the plug 19, and with a thread of line. pitch it will be readily understood thatsuch adjustments may be micrometric. i v V 4 The knives 12, 13 need not necessarily be of the form described and shown. If desired, the adjacent faces of any pair may be plane; or the knives themselves may be circular plates,' mounted in the-relative positions shown.

Y Any suitable metal may b'e'nsed for the construction of the various partsshafts 7 and 8 being of the same metal as before stated. i

Although I have shown two pairs of knives only, it will be understood that any number ofpairs maybe mounted on the shafts 7 and 8, the gear wheelsi5, 6 and 6 being fitted on their respective shafts at any convenient point or points. Further, the shaft 3 and its accessories may. be dispensed with and any suitable method adapted fordriving the shaft 7, or the shaft 8 direct, these shafts being geared together asshownr I I claim-2+ 7 v Apparatus for clearing and cleaning yarns, said apparatus comprising a rotary shaft, circular knives mounted upon the said shaft "to rotate therewith, a second rotary shaftparallel to the first and having circular knives mounted thereon to rotate therewith, the periphery of any circular knife on one shaft overlapping the periphery of any circuiariknife on the other shaft, with a space foryarn to pass between the" overlapping portions of the knives for the clearing or cleaning of said yarn, bearings for the shafts, and means for rotating the two shafts in opposite directions simultaneously.
